Is it burning pain, throbbing pain, deep aching pain, constant or fluctuates- worse after use?
If you can describe more details it could help us to better point you in a direction as far as what to research. Have you ever had any injuries that might have brought these pains on?

Are there any clinics or low income health plans in your area?
Check your state? website {if in USA}or your local government website.
